Can we use more than one form elements in HTML/CSS?

Im really curious if we can. For example if i write

 < p>Write down blabla</p >
<form action=''/blabla''>
blablabla
blabla
bla
</form>
< p>Write down second blablah</ p>
< form action= ''/blabla'' >
blabla
bla
</ form>

Is it ok to use more than one Form element?

Ok thank you, but does it matter what i write in ID? Or i can type what ever words i want?
