Can you form a grignard reagent with 4-bromoaniline 4-bromobenzoic acid or 4-bromophenol when reacted with Mg in ether and why?

The grignard might form but the reagent prefers to act as a base and will undergo hydrolysis and be destroyerd before isolation in reaction with any compound containing OH groups

Why Grignard reagent cannot be prepared by Calcium instead of Magnissium?
The beauty of grignard reagents is their relative ease of production, in simple terms just take an alkyl halide add magnesium and stir to get RMgX which can then be reacted further. The difficulty in using calcium is that the metal itself is less reactive and calcium organometallics are relativelly unstable. Calcium organohalides are also more salt-like and are not as soluble as their Mg counterpart. This whole area is not that well understood, the mechanism of production of grignards is unclear. Certainly alkylcalcium halides are known but they are difficult to prepare and are described as extremely unrreactive.
