Python: IF Statement inside For Loop

I want to create a new column then use another parameter as a condition to populate that column.

Here is my code how ever it doest continue to elif. Only the first argument is applying even though it did not meet the parameter I set.

for i in df_csrdata_2mos_Filtered_Done["Agent"]:
    if i == "unez" or i == "rmbua" or i == "destrada" or i == "amateo" or i == "cmabelison":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 1"
    elif i == "rverga" or i == "dpcaban" or i == "dgsugui":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 2"
    elif i == "gmic" or i == "jdera":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 3"
    elif i == "gras" or i == "mcsrra":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 4"
    elif i == "jcawan" or i == "rmcola" or i == "mjgamo":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 5"
    elif i == "ychaco" or i == "phondra":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 6"
    elif i == "mmorang" or i == "vsin":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 7"
    elif i == "pbong":
        df_csrdata_2mos_Filtered_Done["AgentTag"] = "Agent 8"
    else:
        print("AgentTag Done!")
