FFMPEG - overlay video multiplayer video over a specific period of time

I want to overlay several videos on one video with a given time interval.

tried with a different solution, but it won’t work as an aspect

I use the command below to overlay video by video

String[] cmdWorking3 = new String[]{"-i",yourRealPath,"-i",gifVideoFile1,"-i",gifVideoFile2,"-i",gifVideoFile3,
                "-filter_complex",
                "[0][1]overlay=100:100:enable='between(t,0,2)'[v1];" +
                        "[v1][2]overlay=130:130:enable='between(t,0,2)'[v2];" +
                        "[v2][3]overlay=150:150:enable='between(t,5,6)'[v3];",
                "-map","[v3]","-map" ,"0:a",
                "-preset", "ultrafast", filePath};

using the command above, the first two videos work fine, but the last one will not

Edit:

// Works perfect

 String[] cmdWorking11 = new String[]
                {"-i",
                        yourRealPath,
                        "-i",
                        gifVideoFile1,
                        "-i",
                        gifVideoFile2,
                        "-i",
                        gifVideoFile3,
                        "-i",
                        gifVideoFile4,

                        "-filter_complex",

                        "[1]setpts=PTS+3/TB[1d];" +
                        "[2]setpts=PTS+7/TB[2d];" +
                        "[3]setpts=PTS+10/TB[3d];" +

                        "[0][1]overlay=100:100:enable='between(t,0,2)'[v1];" +
                        "[v1][1d]overlay=130:130:enable='between(t,3,6)'[v2];" +
                        "[v2][2d]overlay=130:130:enable='between(t,7,9)'[v3];" +
                        "[v3][3d]overlay=150:150:enable='between(t,10,13)'[v4];" +

                        "[1]asetpts=PTS+3/TB[1ad];" +
                        "[2]asetpts=PTS+7/TB[2ad];" +
                        "[3]asetpts=PTS+10/TB[3ad];" +
                        "[0:a][1ad][2ad][3ad]amix=4[a]",

                        "-map", "[v4]", "-map", "[a]", "-ac", "5",

                        "-preset",
                        "ultrafast",

                        filePath};

The above command works great fine, but the sound from the overlay video is gone, can you help me solve this problem.

main video Time 00:15 seconds , and all video overlay about 3 seconds .

It would be great to help solve this problem, thanks in advance.
