How many link relationships can give for a single node in genogram?

I need the exact number of relationships links which we can use for a single node.
Please see the below data:
In the below data, m=mother,f=father,ux=wife,vir=husband,h = hostile,la= legally adopted,cs= Close And Strong. s is sex, where s:FM = sex is Focused Male (Patient Male), F = female,M = Male , MC = miscarriage, PA = Abortion, P = Pregnent.

{ key: 0, name: “Patient”,s:“FM”,ux:1,age:70,occupation:“Retired Carpenter”,group:“images/H1.png”},//,h:2
{ key: 1, name: “Patient’s wife”,s: “F”,age:“68”,occupation:“ADL Independent”,group:“images/H1.png”},

	{ key: 2, name: "Pt child 1",s: "M",age:"39",m:1,f:0,h:0},
	{ key: 3, name: "Pt child 2",s: "F",age:"36",m:1,f:0,h:1},//,h:1
	{ key: 4, name: "Pt child 3",s: "F",age:"34",m:1,f:0},
	{ key: 5, name: "Pt child 4",s: "M",age:"32",occupation:"Bank Manager",m:1,f:0,la:0,cs:1,group:"images/H1.png"},
	
	{ key: 6, name: "Pt child 1 Ex-wife",s: "F",age:"30",vir:2,div:2,relationText:"2=d:2008"},
	{ key: 7, name: "Pt child 1 wife",s: "F",age:"28",vir:2,relationText:"2=m:2010"},
	
	//child 1
	{ key: 8, name: "Miscarriage 2011",s:"MC",m:7,f:2},
	{ key: 9, name: "Miscarriage 2011",s:"MC",m:7,f:2},
	{ key: 10, name: "Pt Child 1 male",s:"M",age:"3",m:7,f:2},
	
	//child 2
	{ key: 11, name: "Pt Child 2 hub",s:"M",age:"40",ux:3,relationText:"3=m:2012"},
	
	{ key: 12, name: "",s:"F",age:"4",m:3,f:11,birth:1},
	{ key: 13, name: "",s:"F",age:"4",m:3,f:11,birth:1},
	
	//child 4
	{ key: 14, name: "Pt Child 4 wife",s:"F",age:"28",vir:5,occupation:"Housewife",group:"images/H1.png"},
	
	{ key: 15, name: "Pt Child 4 female",s:"F",age:"3",f:5,m:14,group:"images/H1.png"},
	{ key: 16, name: "Pt Child 4 male",s:"M",age:"2",f:5,m:14,group:"images/H1.png"},
	{ key: 17, name: "Abortion 2018",s:"PA",f:5,m:14,group:"images/H1.png"}

Structure for the above data:

if I remove h:0 in key:2 and given h:2 in key:0,
then structure showing different with no relationships:
See the below structure:

Please help me on this, why h:2 is not accepting to key:0.
And need to know how many number of relations are needed to accept per single node (Symbol).
Please let me know if any clarifications.
