So there's two questions here. Breaking them apart, you have: "Is it okay to ask for relocation compensation for my internship?" and "How do I ask for relocation compensation/assistance?"
To answer the first question ("Is it okay to ask for relocation compensation for my internship?"):
Yes, it's absolutely okay to do so. If you're relocating for work, you should always ask for compensation. However, the likelihood of you receiving that compensation depends entirely on your specific scenario. Maybe your company does not offer that. Maybe they have corporate housing that they will let you stay in for a reduced cost. Nobody on StackExchange can tell you whether or not the company can offer you anything in terms of compensation/reimbursement; that's information that can only come from your employer.
To answer the second question ("How do I ask for relocation compensation?"):
Not like that. If you're going to ask for compensation, ask for compensation - not for information on compensation. If you're still in the contract negotiation phase, treat this just like you would PTO/Salary/Bonuses/etc. If you're beyond that point, you lose some leverage, but it's still a good idea to ask nonetheless.
Make sure that you state that you would like to be compensated for moving for this opportunity, but express that if that is not possible you are still interested in the position.
