Ca+ does not have a noble gas configuration because it does not exist. It needs to be Ca+2 for it to be a noble gas for krypton. The rest have noble gas configuration.
Na+ = [Ne] Rb+ = [Kr] 02- = [Ne] Br- = [Kr] Ca+ = [Ar] 4s1 Al3+ = [Ne] S2- = [Ar] Noble gas configuration is defined as the stable configuration of elements in which 8 electrons occupy the outermost orbital of an orbital. The only exception of this rule is Helium, which needs only 2 electrons to fill its valence (outermost) orbital. Of all the above ions, Ca+ is the only one that does not have eight electrons in its valence, and thus does NOT have a noble gas configuration
Na+=[Ne] Rb+=[Kr] 02-=[Ne] Br-=[Kr] Ca+=[Ar]4s1 Al3+=[Ne] S2-=[Ar] Ca+ does not have noble gas configuration because it does not have all 8 of its electrons to fill the valence. This does not make it a noble gas since noble gasses have all 8 of their valences full making them non reactive.
ohhh i get it noww!!!!! Just Kidding Mr. Pappas:) I swear I'm not just saying this now because I saw all the other posts. Ca+ doesnt have a noble gas notation because Ca is an element which needs 2 electrons to reach a noble gas configuration of Krypton (Kr). Therefore inorder for it to have that configuration it would have to be Ca 2+.

Na+:[Ne] Rb+:[Kr] O2:[Ne] Br:[Kr] Ca+:[Ar]4s1 Al3:[Ne] S2:[Ar] Ca+ Does not have noble gas configuration because its valence shell is not completely filled. It is missing one electron to make it behave like a noble gas.
All of the ions except for Ca+ have completed main energy levels with a stable valence shell of 8 electrons. Ca+ has lost only 1 of its 2 valence electrons, and now is extremely reactive and unstable with 1 valence electron. Therefore it does not have a noble gas configuration with a stable and complete valence shell like the rest of the ions listed above.
