Assuming you are using SPSS and if I understood your question correctly when you do a relaibility test under the ‘statistics’ option you can select the option ” scale if item deleted”.This will give you a new column which gives the Alpha if item is deleted.
Taking your example. your overall score is 0.9023 and you would expect that the individual alpha of each item would be below this. If any of them are above ( lets say 0.9123) that implies that if that item is deleted then you could achive an even higher overall alpha. This variable in question could be eligible for removal.
I hope this answers your question
