Can i have two or more accounts on instagram?

I have an android phone and i have one instagram account, is it possible to get another account? I've heard of Flipagramme but saw that's only for iphone/ipod. So is there a similar app for android?

Old iphone's whatsapp conversations?

My old iphone's screen is black and won't work. It receives calls and vibrates though so the phone is not broken, just the screen. Meanwhile I got another and put my simcard in it. I was wondering if when the old iphone gets its screen fixed, but my simcard is not in it, there's any chance that the conversations that I've been having on my new iphone will be there, or even the ones that were there before I took out the simcard. I wanna know this for whatsapp and iMessage conversations. Please if anyone knows the answer I'd really appreciate it it's important.

How to reset my bluetooth for this speaker?

I have an iPhone 5S, and everything works properly. One time, I was connected to a speaker via bluetooth to play my music and I acidentally tapped "forget this device" instead of normally disconnecting it from the speaker. Now, I can no longer connect to the soeaker from my phone OR iPad. Most websites tell me to "put the device/accessory back into discoverable mode" but I'm not sure how to do that. Can someone please help me fix this?
