Do you think that a lot of people at hogwarts had a crush on Harry? Do you consider him a dreamboat? I like to think that Parvati, Dean and even Neville had a crush on him at some point
Honestly, yes. We know Harry was considered a catch at Hogwarts.
In 4th year before the Yule Ball, multiple girls ask him out (even older ones that didn't need a date to go to the ball):
“Why do they have to move in packs?” Harry asked Ron as a dozen or so girls walked past them, sniggering and staring at Harry. “How’re you supposed to get one on their own to ask them?”
A curly-haired third-year Hufflepuff girl to whom Harry had never spoken in his life asked him to go to the ball with her the very next day. Harry was so taken aback he said no before he’d even stopped to consider the matter. The girl walked off looking rather hurt, and Harry had to endure Dean’s, Seamus’s, and Ron’s taunts about her all through History of Magic. The following day, two more girls asked him, a second year and (to his horror) a fifth year who looked as though she might knock him out if he refused.
Cho Chang seems to have been open to it when he asked her out she declined becouse she already agreed to Cedric:
“D’you — d’you want to go to the ball with me?” said Harry. Why did he have to go red now? Why ?
“Oh!” said Cho, and she went red too. “Oh Harry, I’m really sorry,” and she truly looked it. “I’ve already said I’ll go with someone else.”
And in OotP, Cho clearly was interested in Harry (not in his personality, but in who she thought he was):
“Yes, it’s on Valentine’s Day. . . .”
“Right,” said Harry, wondering why she was telling him this.
“Well, I suppose you want to — ?”
“Only if you do,” she said eagerly.
Parvati was all for going with Harry Potter to the ball. So much so she dragged her sister to be Ron’s date so she could bag the Boy Who Lived:
“Parvati? Will you go to the ball with me?”
Parvati went into a fit of giggles. Harry waited for them to subside, his fingers crossed in the pocket of his robes.
“Yes, all right then,” she said finally, blushing furiously.
“Thanks,” said Harry, in relief. “Lavender — will you go with Ron?”
“She’s going with Seamus,” said Parvati, and the pair of them giggled harder than ever.
Harry sighed.
“Can’t you think of anyone who’d go with Ron?” he said, lowering his voice so that Ron wouldn’t hear.
[...]
“Well . . .” said Parvati slowly, “I suppose my sister might . . . Padma, you know . . . in Ravenclaw. I’ll ask her if you like.”
Who ended up being a disappointing date. Harry being a lousy date didn't stop Parvati and Lavender from thinking Harry is hot though:
Parvati Patil and Lavender Brown, the last two of whom gave Harry airy, overly friendly greetings that made him quite sure they had stopped talking about him a split second before.
And in HBP we see many girls trying to get Harry's attention:
Then he blinked and looked around: He was surrounded by mesmerized girls.
“Hi, Harry!” said a familiar voice from behind him.
“Neville!” said Harry in relief, turning to see a round-faced boy struggling toward him.
The second group was comprised of ten of the silliest girls Harry had ever encountered, who, when he blew his whistle, merely fell about giggling and clutching one another. Romilda Vane was amongst them. When he told them to leave the pitch, they did so quite cheerfully and went to sit in the stands to heckle everyone else.
The third group had a pileup halfway around the pitch. Most of the fourth group had come without broomsticks. The fifth group were Hufflepuffs.
“If there’s anyone else here who’s not from Gryffindor,” roared Harry, who was starting to get seriously annoyed, “leave now, please!”
There was a pause, then a couple of little Ravenclaws went sprinting off the pitch, snorting with laughter.
While I don't think Harry is Hermione's ideal romantic partner, she thinks he is a catch too:
“Oh, come on, Harry,” said Hermione, suddenly impatient. “It’s
not Quidditch that’s popular, it’s you! You’ve never been more interesting, and frankly, you’ve never been more fanciable.”
Ron gagged on a large piece of kipper. Hermione spared him one
look of disdain before turning back to Harry.
[...]
“And it doesn’t hurt that you’ve grown about a foot over the summer either,” Hermione finished, ignoring Ron.
“I’m tall,” said Ron inconsequentially.
And I don't really ship Drarry, as in, I don't really like the dynamic, but I have eyes and I can see Draco can very much be read as having a crush on Harry. I mean, he seeks out Harry on the train literally every year except 6th (& 7th), he seeks Harry out whenever he can in general, and his wand (with a super loyal unicorn core that tends to wilt rather than work for another owner) works for Harry perfectly — which says something about Draco's feelings for Harry. (His behaviour towards Harry kinda reads as pulling pigtails — he just, really wants Harry's attention and goes out of his way to seek it out way too often).
Not sure if Neville had a crush on Harry (I see him as straight), but he definitely looks up to him:
Neville Longbottom, who gave a roar of delight, leapt down from the mantelpiece and yelled. “I knew you’d come! I knew it, Harry!”
Harry is who all the DA look to lead them, though, to know what to do:
“Look who it is! Didn’t I tell you?” As Harry emerged into the room beyond the passage, there were several screams and yells: “HARRY!” “It’s Potter, it’s POTTER!” “Ron!” “Hermione!”
The DA are happy to see Ron and Hermione, but Harry is first, Harry is their figure-head and source of hope, so it's not just Neville and I wouldn't really call it a crush. You can headcanon it, but, it didn't read that way to me.
Dean is a possibility, honestly, but I don't really have any evidence for it, so you could headcanon that too if you want. (It could be funny that Dean and Ginny are dating each other to make Harry jealous because both of them like Harry. They spend their dates talking about Harry).
And obviously, Ginny thinks Harry is a catch.
The point of all of this, is yes, Harry is good-looking by the later books and is considered a catch to various students at Hogwarts since his 4th year. The majority of them, though, don't really know Harry as a person. They see the Boy Who Lived, not Harry, and that's who the majority are attracted to.
