Short answer: yes.
Long answer: it depends on person opinion. There will be people who will say that you're too young, but in my opinion you're perfectly fine. It seems like you're going into this relationship with a clear head and an open mind. If you feel like you're ready for this relationship, and your partner is also ready, then I'd say the age you're at is the right time for you to be dating. The age gap isn't that big, you're not rushing into things or getting too serious too quickly, and there's nothing illegal or immoral about the relationship - so by all accounts you're okay.

There's no minimum (or maximum) age for figuring out your sexuality. People identify as straight when they're as young as you and nobody bats an eye, so why shouldn't you be able to identify as not-straight? Bear in mind that sexuality can change over time so how you feel now may not be how you always feel, but if you're attracted to this girl and you want to pursue a relationship with her, then you're not too young to know that.

As you pointed out, there's no way to know for sure. But from the sounds of it, you're both committed to the relationship and excited to see where it goes, so that's definitely setting you on the right path. My advice is this: don't worry about where the relationship is going for now, just enjoy where it's at. It's easy to stress yourself out thinking about the possibility of it going wrong or of things changing, but it's going to be a lot more fun if you just see how things go. It might work in the long term, it might not, but either way you can enjoy it in the meantime.
