1 and 3 are natural. For 2, more standard is ‘relate to’, not ‘relate with’. ‘Relate with’ exists but is rarer and traditionally has a different meaning (interact). E.g. ‘I relate well with my in-laws. ‘ (I get along with them. I can communicate easily with them.)
Perhaps your use of ‘relate with’ is growing and has achieved regional acceptance in some parts of the English-speaking world but it definitely sounds unnatural to me.
