Thank you!
So, if I understood right my husband will choose the box that he is a petitioner on the form I-864, and my friend then will be the only joint sponsor on the same form, right?

yes

And also if I have some savings on my account, should my friend and my husband mention it? The only concern is how I'm going to prove it, just to print my bank account statement. And it's also not in the US currency. Will they accept it?

If the sponsor's income and assets is insufficient, your (the intending immigrant's) income and assets can be added. If the sponsor's income and assets is sufficient, then there's no need.
