You can claim your 18 year old as a dependent and you will get the $500 credit for other dependents and you can enter the education credit for him on your own return.
22 year old working as a nurse---there is no such thing as claiming her as a dependent for only part of the year. Either she is a dependent for the entire year or is not a dependent. She is the one who is a bit "iffy" since she graduated. Did you pay for over half her support in 2024? Since she was a student for part of 2024, and is under the age of 24, you could claim her. That means on her own tax return she has to say she can be claimed as someone else's dependent. You can enter education credit for her on your own return.
23 year old grad student----can be your dependent; you can enter education credit.
23 year old with job--was not a student in 2024 (correct? --you say he graduated a year ago). If he earned more than $5050 in 2024 he cannot be claimed as your dependent; paying for his insurance is irrelevant.
