Claim parents and sibling as dependents

Can I claim my parents (both over 50 years old) and a younger sibling (over 30 years old) as dependents on my 1040? What deductions or credits would I be eligible for?

 

My parents don't work so they don't have any income (no W-2). They owned a home as their primary residence and I support them financially throughout 2024. My sibling has a low paying job (earning minimum wage) and stays in my primary residence and I occasionally provide some financial support.
